Critics have questioned the ethics behind law enforcement weighing in on marriage issues, with some arguing that it is an unethical interference and that marriage is a private matter that should be kept between the two parties.

Other critics have taken to Twitter arguing in favor of the controversial law, insisting that it acts as an incentive for spouses to remain faithful.

"Go Arizona. They have a adultery law. $500 fine and 30 days in jail. Bet you don't cheat then," Kasi Smith tweeted.

"Just learned Adultery is against the law in Arizona - Class III misdemeanor. I think every state should have this law. #marriage #affair," Chris Shumate wrote.

David was unsympathetic about the prospect of his estranged wife going to jail for cheating on him and suggested it would be a good example for others.

“If they used it all the time, maybe women or men would think twice about going and jumping in the sack and throwing away their marriage,” he told CBS affiliate KPHO.
